"Same-different" responses to arrays cosisting of 2 rows of 1, 3, 5, and 7 colored alpha-numerics were observed over 8 sessions of a four-week period with respect to whether every pair of the upper and lower items had the same attribute of either class (letter and digit) or color (red and blue). In the class attribute, the relation between the number of item-pairs (N) and reaction time (RT) was linear in every condition, and slopes for "same" were 275 msec in 1-2 sessions and 219 msec in 7-8 sessions, while those for "different" were 165 and 112 msec, respectively. These findings supported the hypothesis of the serial self-terminating processing of spatial information from class attribute, though the practice accelerated the processing rates to some extent. In the color attribute, difference between "same" and "different" RTs was not found, and RTs and N were almost independent with each other in 7-8 sessions, though the slope of N-RT function was still significant in early sessions. These suggested that spatial information from color attribute was essentially processed in parallel mode, and the practice had an effect to eliminate some nonessential operations accompanied in early sessions.
